Kickr Core 10 to 11 speed upgrade?
Hi;
First post - I've just upgraded from a Taxc flow to a Kickr Core. I have a Specialized Roubaix with a 10 speed shimano rear cassette to go on the trainer but wondered about just sticking an 11 speed cassette on instead, which would match my normal road bike.
I'm thinking as I'm only fitting the cassette straight onto the trainer I don't need to worry about hubs being incompatible, and maybe need to change the chain; but can I get away without changing shifters or the rear derailleur?
